+# Sprint 11-13: 2. Obergeschoss — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Three fully interactive second-floor rooms (Ultrasound with continuous heartbeat animation, Delivery Room with mama-arrives animation, Nursery with rocking cradles) wired into Main.tscn.
+
+**Architecture:** Floor 2 follows the same side-by-side layout — three rooms at X offsets 0, 1280, 2560 within the `Floor2` node (Floor 2 has only 3 rooms, unlike Floors 0 and 1 which have 4). Two new animated components are introduced: `UltrasoundMachine` (continuous looping heartbeat tween) and `DeliveryBed` (4-state FSM: mama slides in, baby fades in, tap again to reset). `Cradle` adds a rocking rotation animation on tap. `Main.tscn` is updated to replace the Floor 2 placeholder nodes with the real rooms.
+
+**Tech Stack:** Godot 4.6.2, GDScript (static typing), existing `InteractiveObject` base class, placeholder ColorRect graphics.

+## Task 7: Update Main.tscn — wire up Floor 2
+
+**Files:**
+- Modify: `scenes/main/Main.tscn`
+
+**Changes from current file:**
+1. `load_steps` increases from 17 → 20 (add 3 new ext_resources: Ultrasound, DeliveryRoom, Nursery)
+2. Add 3 new ext_resource declarations (ids 16–18)
+3. In the Floor2 section: **remove** the placeholder `Background`, `FloorLabel`, `FloorRect` nodes
+4. **Add** 3 room instances to Floor2 at x offsets 0, 1280, 2560 *(no room 3)*
+5. **Move** ElevatorDown2 from (1200, 360) → (1100, 540) *(consistent with Floor1 pattern)*
+6. **Add** 4 NavigationArrow instances for Floor2 room navigation *(only 2 boundaries, not 3)*
+
+**load_steps arithmetic:** 15 existing ext_resources + 3 new = 18 ext_resources + 1 sub_resource + 1 scene root = 20.
+
+- [ ] **Step 1: Read current Main.tscn**
+
+Read `F:/Development/_gameDev/Cozypaw-Hospital/scenes/main/Main.tscn` to confirm current state before writing.
+
+- [ ] **Step 2: Write the complete new Main.tscn**

+## Self-Review: Spec Coverage Check
+
+| Sprint 11-13 requirement | Covered by |
+|--------------------------|-----------|
+| Ultraschall (sanfte Herzschlag-Animation) | Task 1: UltrasoundMachine with looping scale tween on HeartbeatDot; Task 4: Ultrasound room |
+| Kreißsaal (Mama kommt rein, Baby ist da) | Task 2: DeliveryBed 4-state FSM (tap → mama slides in → baby fades in → tap → reset); Task 5: DeliveryRoom |
+| Säuglingsstation mit Wiegen | Task 3: Cradle with pendulum rotation; Task 6: Nursery with 3 Cradle instances on a rail |
+| All rooms accessible via elevator + horizontal nav | Task 7: Main.tscn with 4 nav arrows for 2 boundaries + ElevatorDown2 |
+| Keine Gift-Mechaniken (product principle) | All interactive objects: GelBottle, Blanket, FlowerVase, BabyBlanket, TeddyBear, MilkBottle — all safe/positive |
+
+**Placeholder scan:** All code blocks complete. No TBD or TODO. Node paths referenced in scripts match scenes:
+- `ultrasound_machine.gd` → `"HeartbeatDot"` — exists as direct child of UltrasoundMachine ✓
+- `delivery_bed.gd` → `"Mama"` (Node2D), `"Baby"` (Node2D) — both exist as direct children of DeliveryBed ✓
+- `cradle.gd` → rotates `self` — no node path lookup needed ✓
+
+**Type consistency:**
+- `_on_mama_arrived()` used as `tween.finished.connect(_on_mama_arrived)` — method callable, matches function signature ✓
+- `Baby.modulate:a` tweened as float — `modulate` is Color, `:a` accesses the alpha channel as float ✓
+- `MAMA_OFFSCREEN_X = -600.0` used in `_ready()` and `_start_reset()` — consistent ✓
+- `MAMA_PARKED_X = -100.0` used only in `_start_arrival()` ✓
+- `rotation_degrees` tweened as float (ROCK_ANGLE = 15.0) — matches `self.rotation_degrees` property type ✓
+
+**Floor2 room count:** 3 rooms (not 4). Nav arrows: 4 total (2 boundaries × 2 directions). ElevatorDown2 only (no ElevatorUp2 — Floor 2 is the top floor). ✓
+
+---
+
+## Smoke Test Checklist (manual, on device after completion)
+
+- [ ] Elevator from Floor 1 lands at Floor 2 Ultrasound room
+- [ ] Heartbeat animation starts automatically on entering Ultrasound room (green dot pulses every ~0.84s)
+- [ ] "→" navigates Floor 2: Ultrasound → DeliveryRoom → Nursery and back with "←"
+- [ ] No "→" arrow visible in Nursery room (no room 3)
+- [ ] Tapping DeliveryBed: Mama slides in from left, Baby appears
+- [ ] Tapping DeliveryBed again: Mama slides out left, Baby disappears
+- [ ] Tapping DeliveryBed during animation: nothing happens (state guard)
+- [ ] Tapping any Cradle: cradle rocks (swings ±15°, returns to center)
+- [ ] Tapping Cradle during rocking: nothing (state guard)
+- [ ] All interactive objects (GelBottle, Blanket, FlowerVase, BabyBlanket, TeddyBear, MilkBottle) bounce on tap
+- [ ] Elevator Down from Floor 2 → Floor 1 XRay room
+- [ ] Bunny can be dragged to Floor 2
